75 degrees is approximately 1.3080 radians.
Converting degrees to radians involves multiplying the degree value by π divided by 180. This is because a full circle is 2π radians, which equals 360 degrees. So, to find radians from degrees, the formula is: radians = degrees × (π / 180).

Conversion Formula
The formula to convert degrees to radians is radians = degrees × (π / 180). This works because 180 degrees equals π radians, meaning the ratio between degrees and radians is π divided by 180. When you multiply degrees by this ratio, you get the equivalent in radians.
For example, for 75 degrees, multiply 75 by π/180: 75 × (π / 180) ≈ 75 × 0.0174533 ≈ 1.3080 radians. This step-by-step ensures accurate conversion by scaling the degree measure to its radian equivalent based on the circle’s properties.
Conversion Example
- Convert 45 degrees to radians:
- Multiply 45 by π/180
- 45 × (π / 180) = 45 × 0.0174533
- Result = 0.7854 radians
- Convert 90 degrees to radians:
- Multiply 90 by π/180
- 90 × 0.0174533 = 1.5708 radians
- Convert 120 degrees to radians:
- Multiply 120 by π/180
- 120 × 0.0174533 = 2.0944 radians
- Convert 180 degrees to radians:
- Multiply 180 by π/180
- 180 × 0.0174533 = 3.1416 radians

Conversion Definitions
Degrees: A unit measuring angles, where a full circle equals 360 degrees, used in navigation, geometry, and everyday contexts to specify angles or directions.
Radians: A measure of angle based on the radius of a circle, where one radian equals the angle subtended by an arc equal to the radius length, making it the natural unit of angular measurement in mathematics.
Conversion FAQs
Why is π used in converting degrees to radians?
π is used because it represents half a circle in radians; since 180 degrees equals π radians, it provides a direct ratio to convert degrees into the more math-friendly radian units, simplifying calculations involving angles.
Can I convert degrees to radians without a calculator?
Yes, by multiplying the degree value by π/180, you can do the conversion manually. For approximate results, use 3.1416 for π and multiply accordingly, which is helpful in quick estimations or when calculators are unavailable.
What applications require converting degrees to radians?
Many fields like physics, engineering, and computer graphics use radians for calculations involving rotation, oscillations, and wave functions, because radians provide a more natural measure based on circle properties, making formulas more straightforward.
